Home Forums Programming XML Query to select records from Xml column RE: Query to select records from Xml column

  • Hello Everyone,

    I have same requirement as the above one please look into it and suggest me the solution.

    I have a table with 4 columns. out of which first three columns are nvarchar and last column is XML type.

    Table Structure is given below,

    FName        LName       Gender         ItemPriceTag
     A1                 B1              M              (Item = "Soap"   Price=23), (Item = "Ball"   Price=31), (Item = "Book"   Price=98)
    A2                 B2              F              (Item = "Soap"   Price=45), (Item = "Ball"   Price=19), (Item = "Book"   Price=45)
    A3                 B3              M              (Item = "Soap"   Price=12), (Item = "Ball"   Price=11), (Item = "Book"   Price=18)
    A4                 B4              F               (Item = "Soap"   Price=54), (Item = "Ball"   Price=65), (Item = "Book"   Price=98)

    I am stroring my first 3 columns as nvarchar, I want to store last column as XML type, becuase it may contain the data upto 250 items.

    My first question is what is the proper structure to store the data in XML format. i am using the below format, I feel that is wrong, please look into it and suggest me whether it is correct or wrong. If it is wrong, please suggest the proper way to store the data.

    for XML column im storing data as, (Since i am concerned on last column, i am mentioning only last column)
    <ItemPriceTag><Item= "Soap"><Price>23</Price></ItemPriceTag>
    <ItemPriceTag><Item= "Ball"><Price>31</Price></ItemPriceTag>
    <ItemPriceTag><Item= "Book"><Price></Price></ItemPriceTag>.   this is for first row

    <ItemPriceTag><Item= "Soap"><Price>45</Price></ItemPriceTag>
    <ItemPriceTag><Item= "Ball"><Price>19</Price></ItemPriceTag>
    <ItemPriceTag><Item= "Book"><Price>45</Price></ItemPriceTag>  this is for 2nd row  .......etc

    Second question is, I want to display each item as a column name and price as its value.
    For eg:

    FName        LName       Gender         Soap       Ball        Price
     A1                 B1              M              23            31          98
    A2                 B2              F                45           19           45
    A3                 B3              M               12            11          18
    A4                 B4              F               54            65           98

    Please suggest me the table structure and solution for the above requirement.

    Thanks in advance,
